Davis, 30, has two years left on the five-year contract extension he signed in 2010, with scheduled compensation of $5.3 million - including a $4.7 million base salary, $200,000 workout bonus and $400,000 in per-game roster bonuses - in 2014.

"Always great to have Vernon on the field. He looks good, excited to have him back out here," quarterback Colin Kaepernick said. "Vernon's a Pro Bowl tight end. He's one of the best in the league. There's not going to be too much of a fall off for him. I don't think anyone's concerned about that. We're just happy he's here."

That puts him among the NFL's highest-paid at his position, but shy of the $10 million per year average the New Orleans Saints gave Jimmy Graham on a new deal last week. Davis explained last month in a column on TheMMQB.com that he intended to hold out because: "It's all about getting paid what you deserve."

Perhaps Davis was influenced by the 49ers' willingness to negotiate with a player who never threatened to hold out: left tackle Joe Staley, whose deal was extended and restructured to include $10 million in new guarantees last week.

San Francisco guard Alex Boone also wants a new deal and did not report Wednesday. The 49ers begin practice Thursday.
